Agni-IV ("Fire") is the fourth in the Agni series of missiles which was earlier known as Agni II prime. It has been developed by India's DRDO and displayed a number of new technologies and significant improvement in missile technology. The missile is light-weight and has two stages of solid propulsion and a payload with re-entry heat shield. [9] With 4,000 km range, [10] it is capable of striking targets in nearly all of mainland China, if launched from northeastern part of India. [11]

Development

This missile is one of a kind, proving many new technologies for the first time, and represents a significant leap in India's missile technology. The missile is lighter in weight and uses a two-stage rocket engine powered by solid propellant. The Composite Rocket Motor which has been used for the first time has given excellent performance. The missile system is equipped with modern and compact avionics with redundancy to provide a high level of reliability. The indigenous-built ring laser gyroscope is used in the high accuracy with Micro Inertial Navigation System (MINGS), which complement each other as a redundancy. [12] The high performance onboard computer with distributed Avionics architecture, high speed reliable communication bus and a full Digital Control System have controlled and guided the missile to the target. The missile reached the target with a high level of accuracy. Radars and electro-optical systems along the Coast of Odisha have tracked and monitored all the parameters of the missile. Two Indian Naval ships located near the target witnessed the final event.

Dr Vijay Kumar Saraswat, Scientific Advisor to Raksha Mantri, Secretary, Department of Defence R&D and Director General DRDO, who witnessed the launch, congratulated all the scientists and employees of DRDO and the Armed Forces for the successful launch of AGNI-IV. Sri Avinash Chander, Chief Controller (Missiles & Strategic Systems), DRDO and Programme Director of AGNI, while addressing the scientists after the launch, called it as a new era in the modern Long Range Navigation System in India. He said, "this test has paved the way ahead for the success of Agni-V Mission, which will be launched shortly".

Project Director of Agni-IV, Tessy Thomas with her team prepared and integrated the missile system and launched the missile successfully. According to her, DRDO has produced and proven many new state of the art technologies in the Missile System like Composite Rocket Motors, very high accuracy Ring Laser Gyro based Inertial Navigation System, Micro Navigation System, Digital Controller System and very powerful onboard computer system. The missile, having capability to carry strategic nuclear warheads for the forces, has provided a fantastic deterrence to the country and it will be produced in numbers and delivered to the Armed Forces as early as possible. Sri S.K. Ray, Director RCI, Sri P. Venugopalan, Director DRDL, Dr V.G. Sekaran Director ASL and Sri S.P. Dash, Director ITR were also present during the launch and reviewed all the activities.

The DRDO had produced and proven many new state of the art technologies with the Agni-IV like composite rocket motors, very high accuracy Ring Laser Gyro based Inertial Navigation System, Micro Navigation System, Digital Controller System and very powerful onboard computer system. [9] Agni-IV bridges the gap between Agni-II and Agni-III. Agni IV can carry a warhead of 1 tonne. It is designed to increase the kill efficiency along with a higher range performance. Its length is 20 meters and launch weight 17 tonnes. It can be fired from a road mobile launcher. [13] [14] Efforts are being made to fine-tune the Agni missiles to defeat anti-ballistic missile systems. The radar cross-section and other detectable signatures of Agni-IV have been significantly reduced to make them much more immune to counter-measures. [15]

Testing

Agni-IV has undergone seven successful tests over the course of six years. [16]

An intercontinental ballistic missile (ICBM) is a ballistic missile with a range greater than 5,500 kilometres (3,400 mi), primarily designed for nuclear weapons delivery. Conventional, chemical, and biological weapons can also be delivered with varying effectiveness, but have never been deployed on ICBMs. Most modern designs support multiple independently targetable reentry vehicle (MIRVs), allowing a single missile to carry several warheads, each of which can strike a different target. The United States, Russia, China, France, India, the United Kingdom, Israel, and North Korea are the only countries known to have operational ICBMs.

The Strategic Forces Command (SFC), sometimes called Strategic Nuclear Command, forms part of India's Nuclear Command Authority (NCA). It is responsible for the management and administration of the country's tactical and strategic nuclear weapons stockpile. It was created on 4 January 2003 by the Vajpayee Government. Air Marshal Teja Mohan Asthana became its first commander-in-chief.

The project started in 1982–83 under the leadership of Abdul Kalam who oversaw its ending in 2008 after these strategic missiles were successfully developed.

<span class="mw-page-title-main">Agni-II</span> Indian medium-range ballistic missile

Agni-II, is the second strategic ballistic missile of the Agni family envisaged to be the mainstay of the Indian missile-based strategic nuclear deterrence. The Agni-II is a medium-range ballistic missile (MRBM) with two solid fuel stages and a Post Boost Vehicle (PBV) integrated into the missile's Re-entry Vehicle (RV). The Agni's manoeuvring RV is made of a carbon-carbon composite material that is light and able to sustain high thermal stresses of re-entry, in a variety of trajectories. The Agni-IIA is a more advanced version of Agni-II, albeit with more sophisticated and lighter materials, yielding a better range and operating regime. Agni-IIA was later renamed as Agni-IV plugging the gap between Agni-II and Agni-III. While the first test of Agni-IV in December 2010 was a failure, the second test flight in November 2011 was a success Agni-II, developed as part of medium- and long-range Agni series of missile systems, has already been inducted into the Armed Forces.

The Agni missile is a family of medium to intercontinental range ballistic missiles developed by India, named after one of the five elements of nature. Agni missiles are long-range, nuclear weapons capable, surface-to-surface ballistic missiles. The first missile of the series, Agni-I was developed under the Integrated Guided Missile Development Programme (lGMDP) and tested in 1989. After its success, the Agni missile programme was separated from the GMDP upon realizing its strategic importance. It was designated as a special programme in India's defence budget and provided adequate funds for subsequent development. As of November 2019, the missiles in the Agni series are being inducted into service. The family comprises the following:

The K family of missiles, is a family of submarine-launched ballistic missiles (SLBM) developed by India to boost its second strike abilities and thus augment its nuclear deterrence. Information about this family of missiles has mostly been kept classified. It is reported that 'K missiles' are faster, lighter and stealthier than their Agni missile counterparts. High Energy Materials Research Laboratory (HEMRL) developed a new formulation of composite propellant that is more efficient and provide greater thrust compare to Agni missile series. The objective behind the development is to make K missile family faster and lighter without compromising on operational range.

India has studied, produced and used various strategic and tactical missile systems since its independence. Decades long projects have realised development of all types of missile systems including ballistic, cruise, anti-ship, air-defence, air-to-air and anti-missile systems. India is one of seven countries in the world with intercontinental ballistic missiles (ICBMs) and one of four countries with anti-ballistic missile systems. Since 2016, India has been a member of Missile Technology Control Regime (MTCR).
